Background: Concern has been raised regarding the mounting collective radiation doses from computed tomography (CT), increasing the risk of radiation-induced cancers in exposed populations. Purpose: To compare radiation dose and image quality in a chest phantom and in patients for the diagnosis of pulmonary embolism (PE) at 100 and 120 peak kilovoltage (kVp) using 16-multichannel detector computed

This article examines the expansive commercialization of various neospiritual and pseudoscientific practices currently mobilized in late modern Swedish pursuits of identity, meaning, and health. The focus is on the emergence and marketing of new entrepreneurs who have established themselves as “coaches” promoting personal development, and how they organize their own systems of education and certif

Popular Abstract in Swedish Mögel i byggnader är ett vanligt problem som kan orsaka en dålig innemiljö och påverka hälsan hos de personer som vistas i byggnaden. Kostnaderna för att åtgärda problemen kan vara omfattande. Att redan vid planeringsstadiet av en byggnad ta hänsyn till risker för mögelväxt kan leda till minskat antal mögelskador i framtiden och ett mer hållbart byggande. Mögelväxt är The susceptibility to mould growth varies between building materials. The factors that most affect mould growth, the relative humidity (RH) and temperature also vary in different parts of buildings. One way of preventing the growth of mould in buildings is therefore to choose building materials that can withstand the expected conditions. It is thus crucial that data are available to allow the corr

The use of factor-augmented panel regressions has become very popular in recent years. Existing methods for such regressions require that the common factors are strong, an assumption that is likely to be mistaken in practice. Motivated by this, the current paper offers an analysis of the effect of weak, semi-weak and semi-strong factors on two of the most popular estimators for factor-augmented re

Popular Abstract in Swedish Hos barn med cerebral pares (CP) spastisk diplegi är förhöjd muskelspänning s.k. spasticitet är ett vanligt symptom som påverkar kvalitén på rörelser. Muskler blir stela och förkortas och felställningar i leder kan uppstå. Selektiv Dorsal Rhizotomi (SDR) är ett ingrepp som används för att minska spasticitet i benen och som i kombination med sjukgymnastik kan ge beståendThe overall aim of the thesis was to describe long-term development of functional outcomes in children with cerebral palsy undergoing selective dorsal rhizotomy (SDR) combined with physiotherapy and to evaluate measures used in follow-up. Five years after SDR muscle tone was reduced, passive range of motion (PROM) increased in hip, knee and foot, gross motor function measured by the Gross Motor F

Popular Abstract in Swedish Utgångspunkten för denna avhandling är passet som det utformades och användes i den Europeiska Unionen från 1999 till 2001, närmare bestämt som en förutsättning för att få passera EU:s yttre gränser och som en symbol för ett förenat Europa fritt från medlemsstaternas spektakulära nationalism. Enligt nationalismen skulle varje nation ha sin egen stat och varje stat skulThe vantage point for this thesis is the passport as it was understood and used in the European Union from 1999 to 2001, as a requirement to cross the external borders of the EU and as a symbol of a united Europe free from a spectacular nationalism of the member states. According to nationalism, every nation should have its own state, and every state should be legitimized by a nation. If the mode

This article expands current acquisition literature to include sociocultural challenges on inter-organizational levels following acquisitions of young, innovative firms. Socioculture here denotes network parties' shared values, belief systems, and practices. Three acquisitions illustrate their consequences. The young, innovative firms and their acquirers are part of different networks, have dissim

Literacy practice and discursive practice are two distinct concepts, belonging to different research traditions (new literacy studies, NLS, and critical discourse analysis, CDA). This article is an effort to enlighten the discussion of these concepts by comparing the history and scope of the concepts, the research interest and the different research methods used. Exemplifying with an analysis of 1

Context. Stars are born together from giant molecular clouds and, if we assume that the priors were chemically homogeneous and well-mixed, we expect them to share the same chemical composition. Most of the stellar aggregates are disrupted while orbiting the Galaxy and most of the dynamic information is lost, thus the only possibility of reconstructing the stellar formation history is to analyze th

Accurate assessment of energy expenditure (EE) is important for the study of energy balance and metabolic disorders. Combined heart rate (HR) and acceleration (ACC) sensing may increase precision of physical activity EE (PAEE) which is the most variable component of total EE (TEE).

In the first three years of the physics program at the relativistic heavy ion collider (RHIC) a picture was established in which the suppression of hadrons at high transverse momenta (pT) in central Au+Au collisions is explained by energy loss of quark and gluon jets in a medium of high color-charge density. Measurements of single-particle spectra for a smaller nucleus (Cu), for different center-o

The spin waves in the multi-k antiferromagnet USb soften and become quasielastic well below the antiferromagnetic ordering temperature T-N. This occurs without a magnetic or structural transition. It has been suggested that this change is in fact due to dephasing of the different multi-k components: a switch from 3-k to 1-k behavior. In this work, we use inelastic neutron scattering with tridirect

This paper reports on a numerical study of the thermodynamic and basic combustion characteristics of oxy-fuel combustion in gas turbine related conditions using detailed chemical kinetic and thermodynamic calculations. The oxy-fuels considered are mixtures of CH4, O-2, CO2 and H2O, representing natural gas combustion under nitrogen free gas turbine conditions. The GRI Mech 3.0 chemical kinetic mec

The general concern for the state of the environment sets requirements on strategies developed by companies to curb environmental and social impacts of their activities. One of the most notable changes in the way companies work with sustainability issues is the shift of the focus from own operations to improving the performance of supply chains. This paper aims to analyse the practise of corporate

We present measurements of electrons and positrons from the semileptonic decays of heavy-flavor hadrons at midrapidity (vertical bar gamma vertical bar < 0.35) in Au + Au collisions at root(NN)-N-S = 62.4 GeV. The data were collected in 2010 by the PHENIX experiment that included the new hadron-blind detector. The invariant yield of electrons from heavy-flavor decays is measured as a function of t

Purpose – The aim of this paper is to inquire into the management of construction supply chains by directing attention toward the different types of interdependencies that exist in such chains and in construction projects. Design/methodology/approach – The paper is developed as part of two ongoing research projects on supply chain management (SCM) in construction. A case study approach is used fo

We report two cases of Streptococcus pneumoniae-associated hemolytic uremic syndrome (SP-HUS) caused by serotype 3. One case occurred in an unvaccinated boy and 1 in a girl vaccinated with the 13-valent pneumococcal conjugate vaccine. SP-HUS must be considered in children, and conjugate vaccines may be less effective against serotype 3 than other serotypes.
